The abillities Cloud Nine and Air Lock were both added in Generation III, even though they have the same effect. The abillity Soundroof was also added in Generation III and the abillity Cacophony was planned for the third generation. Soundproof and Cacophony would have had the exact same effect.

In pokemon GSC If you traded yourself a Missingno from RGBY the Missingno would convert itself into a johto region pokemon and if you traded a johto region pokemon to RGBY it would convert into a missingno.

And in order to trade a GSC pokemon to RBY you need to preform something called the Johto Guard glitch, which involves doing the Celebi glitch first to obtain a the GSC glitch pokemon with an index number of 255, which has the ability to hide everything in the party below it.
